Original No. 1,397,929, dated November 22, 1921, Serial No. 411,516, filed September for reissue filed May 24,

To all 'w ham it may concern:

Be it known that I, CHAR ES A. Gnonns, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Carbonators and Draft Arms for Soda ater, of which the following is a specification. 5

This invention relates to dispensing apparatus such as is used in soda-water fountains and consists more particularly in certain improvements I have made in the means for carbonating the water and dispensing the charged liquid.

One of the objects of the invention is to control the carbonating solely bythe movements of a single draft arm or dispensing handle whereby the amount of liquid and gas deliveredto the charging chamber is governed by the amount of carbonated liquid withdrawn from the said chamber.

Other objects and advantages will appear in the course of the following description in which reference is made to the accompanying drawing in which:

Fig. 1 is a perspective view, partly broken away, of a dispensing apparatus or soda fountaian equipped with improvements embodying my invention;

Fig. 2 is an enlarged view partly in sec-. tion and partly in elevation showing the arrangement of parts constituting my invention, the passageways or ports in the valve casing being shown in displaced or distorted position for convenience of illustration;

Fig. 10 is a View in cross section taken on the line 10-10 of Fig. 5.

Similar reference numerals indicate corresponding parts throughout the drawings.

Referring to the drawings: 1 designates a base upon which the various parts of the apparatus are supported. 3 designates a tubular member supported upon said base, and 4 a standard upon which is supported the valve casing 5 of the faucet 6 designates the handle or draft arm, which is mounted on the outer end of a square shaft 7, the inner end of which is connected with the rotatable valve 8. The said valve is slidable on the inner end of said shaft so that it may be pressed against its seat by a screw 9 provided with means, such as a spring arm 10 engaging serrations formed on a washer or head 11 carried by the shaft 7, to secure or hold it in adjusted position.

' 13 is the discharge tube of the faucet into which open the outlet passages 141 in the valve casing (see dotted lines in Fig. 5') and depending in which is the gas vent tube 15, carrying the cup 16 and communicating with the vent port in the valve casing hereinafter described, The member 3 is divided into upper and lower chambers 20 and 21 by means of a partition 22 through which is an opening or passageway 23 which is adapted to be closed upwardly by a ball check valve 24 which is adapted to be retained in operative relation to the opening 23 by the screen support 60. Water or other liquid is adapted to be supplied to the chamber 20 through a supply pipe 25, which pipe is provided with a downwardly closing check valve, the casing of which is shown at 26. By means of a pipe 27 leading from the valve casing of the faucet to an opening in the upper end of the chamber 20 gas is adapted to be supplied under pressure to said chamber to drive or force the water therefrom through the opening or passageway 23 into the chamber 21. The opening in the upper end of the chamber 20 through which gas is adapted to be supplied thereto is'adapted to be closed by an upwardly closing check valve 28. The pipe 27 also serves the function of conveying gas from thechamber 20, when 20, 1920. Application casing a1id valve 8 to the vent tube from which it is discharged, the ball check valve 28 t, 1 ime dr pp o upon the c en. si ppqr p v ded he he valve 8 at such time is in open position because the pressure of the gas in the chamber 20 is not suflicient to raise the same. 29 is another gas supply pipe leading from the valve casing 5 of the faucet into the lower chamber 21 of the tubular member 3 in which chambergas is absorbed by the liquid which is introduced therei-nto from the chamber 20. Such chamber, 21 therefore, may be. regarded and designated as the primary absorption chamber "of the apparatus. Theend of the gassupply pipe 29within the chamber 21 is bent and. perforated as shown at3O in. Fig. 2., 31 is a branch pipe, leading from the pipe 29. into the top of the lower chamber 21 which branch pipe is provided. with, an outwardly closing, check valve, the casing of which is indicated, at 32. Gas may enterthe upper portion of the. chamber 21 from the, 29through the pipe 31. The outwardlyclpsingvalve indicated. at 32 prevents outflow of any gas which may happen to be in the. chamber 21 above. the top surface of any liquid; which may also be present therein.

33 designates a gas supply pipe leading from a gas tank 34 (see Fig. 1) into the valve casing 5 of the faucet, and 35 designates a pipe which leads from the bottom of the absorption chamber 21 to the first of a number of secondary absorption chambers; 36, six ofwhich are shown in the drawings; but it will be understood that the number may be varied as desired.

These secondary absorption chambers contain a plurality of screens, such as shown at 37 in Fig. 3, and one or all of them may also contain inverted truncated cones 38 closed at their lower ends by screens 39 to assist in the mixingof the gas and liquid, such as water; that is, in the charging of the liquid. These secondary absorption chambers are connected in series by the pipes 40' running from the bottom of each of them to the top of the next succeeding one, as shown in Fig. 2, and. from the last. of the. series a pipe 41 extends to the valve. casing.

As already indicated, the. initial or first mixing of the gasand the liquid takes place in the first or primary absorption chamber 21 in which initial absorption is effected, and for the purpose of effecting a. more intimate association ofthe gas. with and a more complete absorption thereof by the liquid,

, the secondary absorption chambers 36' are provided, the number 015 which may be varied,

as above stated.

The valve casing 5 contains the passages or por t s;42, 43;,- 44, 41 46, and. 47;, and the valve 8 contains the passages or ports 52, 53, 54, 55, 56, 57 and 58.

49 is the usual fixed washer between the valve 8 and its seat in the valve casing The gas supply .pipe 33 communicates with the port or passage 42 in, the valve seat which when the valve is in open pofiition registers with the port 52 in the valve which is connected with the port'53 in the latter, and the port 53 registers at such time with the port 43 of the casing which leads to the pipe 29. Thus it will be seen that when the valve 8 is in open position a continuous passageway is afforded for the as from. the tank 34 to the absorption cham er 21. When the valve is in open position as just described the charged liquid in the pipe 41, which leads to the port or passage 44 in the valve casing, passes out through the port 54 in the. valve and through a. passage therein to the, port 55*, which registers with the port 45 in the casing which leads to the discharge outlets 14 which open into the discharge tube. 13. Also when the valve is in open position. the port 46 in. the casingwhich leads from the vent tube 15 registers with the port 56 in the valve, which port is connected by a passage through the valve withthe port 57 in the. latter which registers with the port 47 in the seat. The port 47 leads to the pipe 27 which is connected with thechamber 20 whereby any gas which may have accumulated or which may be present in the latter may escape therefrom and be discharged through the vent tube 15 The opening of said passageway permits the gas withinthe chamber 20 to expand and flow outthrough the pipe 27 and vent tube 15 thereby relieving the pressure within said chamber 20. and permitting liquid to flow freely into said chamber from. the pipe 25.

When the valve 8 is in closed or shut position, as shown in Figs. 5 and 7, the passage-way through the valve leading to the pipe 29 is closed so that no gas can at such time be delivered to the. chamber 21. At such time the port 42 in the valve seat, wit-h which the gas outlet 33 communicates, registers with the port 58 in the valve disk 8, which port is connected by a passageway with. the port 52 also in the valve disk, which communicates with the port 47 in the. valve seat and then through the pipe 27 to the upper end of the chamber 20. and forces the liquid which may have entered said chamber during the period when the valve 8 was in open position through the check valve. controlled opening'or passageway 23 into the absorption chamber 21. When the valve is in this shut position all other ports or passageways in both the valve seat and the valve disk are closed.

The operation of the apparatus may be recapitulated briefly as follows: When the valve is opened gas is admitted into the lower chamber 21 wherein it is mingled with the liquid previously discharged into said chamber through the opening or passageway 23 from the liquid-receiving chamber 20. The said gas is discharged into the body of said liquid. In the said chamber 21 initial and partial absorption takes place. The liquid is forced bythe pressure of the gas from the said chamber 21 through the pipe intothe first of the secondary absorption chambers 36 wherein the charging is completed and the gas thoroughly intermingled with and charged into the liquid and absorbed thereby. At the same time the gas from the upper chamber is vented through the pipe 27 to the vent tube 15 from which it is discharged and is permitted to intermingle and mix with the charged liquid which is being drawn from the faucet through the discharge tube 13. Simultaneously liquid, such as water, is'being delivered through the supply pipe 25 into the liquid-receiving chamber 20. Immediately upon the closing of the valve by means of the handle or draft arm 6 all of the passages through the valve structure are closed with the exception of those passages leading from the gas supply pipe 33 through the valve casing 5 and valve 8 to the pipe 27 so that during the period or time when the valve is in closed or shut position the liquid is forced from the chamber 20 into the absorption chamber 21. It will be seen that during the time that the valve 8 is in shut position the gas supply tank is in communication with the liquid-receiving chamber 20 and through the opening or passageway 23 with the absorption chamber 21 and exerts pressure upon the liquid therein so that a certain amount of absorption takes place, but such pressure cannot effect flow of the liquid from the said chamber at such time or during such period because the outlet from the absorption chambers is closed thus preventing the passage or flow of liquid through the absorption chambers.

It will be seen that the valve structure constitutes a controlling means intermediate the gas supply and the chambers 20 and 21 and that by the operation of the single valve member 8 to open and close the same I am enabled by my invention to control the delivery of liquid and gas to the absorption chamber and also to control the delivery of charged liquid from the absorption chamber or chambers. It will be understood that when the absorption chamber or chambers is or are once filled with charged liquid the amount of uncharged liquid which may be delivered to the said chamber or chambers is dependent upon the amount of charged liquid which may be withdrawn therefrom.

It will now be apparent that I have devised a novel apparatus for carbonating and dispensing liquids, such as soda-water, which embodies the features of advantage enumerated as desirable in the statement of invention and the above description, and while I ing from the spirit or scope of the invention or sacrificing'any of its advantages.
